In more modern times Croydon has developed an important centre for shopping, with the construction of the Whitgift Centre, which opened in 1969. The Fairfield Halls arts centre and event venue opened in 1962. The Warehouse Theatre opened in 1977. The 1990s saw further changes intended to give the town a more attractive image. These include the closure of North End to vehicles in 1989 and the opening of the Croydon Clocktower arts centre in 1994. Tramlink began operation in May 2000. A new equally large shopping centre, Centrale, opened in 2004 opposite the Whitgift Centre, straddling the site of the smaller Drummond Centre and what was once a large branch of C&A. There are plans for a large new shopping centre, Park Place, which will replace most of the eastern edge of the shopping district including St George’s Walk; the redevelopment of the Croydon Gateway site; and extensions of Tramlink to Purley, Streatham, Lewisham and Crystal Palace. Croydon has become the second-largest place to shop in the south east, after central London, offering a wide range of shops and department stores. It is also home to many high density buildings such as the Nestlé Tower, being London’s third main CBD, after the Square Mile and the Docklands and South London‘s main business centre. The Croydon area is served by various hospitals of which the main one is Mayday University Hospital in London Road. The Mayor of London, Boris Johnson, said he would support Croydon becoming an official city.
